However, those skilled in the relevant art will also appreciate that the thickness of the reinforcing layer 120 can be adjusted as appropriate.

In some embodiments, the outer layer 130 is made of a first polymer. The first polymer may be a polymer having good wear resistance, corrosion resistance and weather resistance characteristics. Among them, wear resistance refers to the wear resistance of the material. For example, when the hose is in use, there may be multiple ways to cause wear of the outer layer 130, such as abrasive wear, adhesive wear (gluing), fatigue wear (pitting), corrosion wear, and the like. Corrosion resistance reflects the corrosion resistance of the material. For example, microbes in high temperature environments, high temperature environments, and corrosive fluids formed by rainwater combined with other materials can corrode materials. Weatherability refers to the ability of a material to withstand a variety of outdoor factors. For example, when materials are placed in outdoor conditions, a variety of outdoor factors such as light, temperature changes, wind and rain, bacterial damage, etc., can cause aging of materials such as fading, discoloration, cracking, chalking, and strength reduction.

In some embodiments, the first polymer may include, but is not limited to, a polyurethane-based material, a polyvinyl chloride and a derivative thereof, a rubber-based material, a resin and a general-purpose high molecular polymer, an amide high polymer, and an imide. Polymers, etc. Among them, polyurethane materials include, but are not limited to, thermoplastic polyurethane (TPU).

In some embodiments, the mass ratio of PVC to powdered NBR can be from 100:0 to 50. In some embodiments, first The polymer can be a TPU. TPU is lighter in weight and has excellent wear resistance, corrosion resistance, weather resistance and low temperature flexibility. Those skilled in the relevant art will appreciate that other rubber or thermoplastic materials can also be used in the manufacture and production of the outer layer without departing from the spirit of the present application. In some embodiments, the outer layer 130 has a thickness between 0.1 mm and 5.0 mm. However, those skilled in the relevant art will also appreciate that the thickness of the outer layer 130 can be adjusted as appropriate. In some embodiments, the material of outer layer 130 and inner layer 110 may be the same, for example, outer layer 130 and inner layer 110 may each employ a TPU. In some embodiments, the materials of outer layer 130 and inner layer 110 can be different.

In order to make the hose 100 more visible or recognizable in the field, especially at night, a luminous layer or a reflective layer 140 may be provided on the surface of the outer layer 130. After the reflective layer is disposed on the surface of the hose 100, the reflective layer can be reflected when there is a light source at night, for example, reflecting the moonlight, or reflecting the corresponding light when the worker uses a flashlight, a car light, etc., thereby making the hose easier. Identified. After the luminous layer is placed on the surface of the hose 100, the luminous layer absorbs sunlight or natural light during the day and then emits night light when the light is insufficient at night, so that the hose is more easily recognized at night.

The luminous effect of the luminous layer is mainly realized by luminous powder (phosphor), such as photo-energy storage luminous powder. In some embodiments, the luminous powder may be sprayed directly onto the surface of the outer layer 130, or the luminous layer may be disposed on the outer surface by coextrusion. In some embodiments, the material of the luminous layer may include: a first polymer (eg, TPU, PVC, etc.), a luminous powder, a Si-69 (silane) coupling agent, an antioxidant, and an MDI curing agent, the above material configuration may be The luminous layer is better placed on the outer surface by coextrusion. Wherein, the first polymer is the same material as the outer layer 130 of the hose, and the luminous layer and the outer layer 130 can be more easily combined. The Si-69 (silane) coupling agent can activate the surface of the luminous powder to increase the adhesion of the luminous powder to the outer layer 130. Antioxidants enhance the oxygen resistance of the material and increase its service life. The MDI (diphenylmethylene diisocyanate) curing agent can increase the degree of crosslinking of the TPU at a high temperature, so that the TPU produces a network structure, so that the luminous layer and the outer layer 130 of the hose are better bonded.

For example, one or more whistles may be placed at the surface of the hose, which can sound when the wind blows, thereby providing a warning and guidance. As another example, one or more buzzers or speakers may be provided on the surface of the hose. The buzzer or speaker may be powered by a DC power source such as a battery or an alternating current source such as a grid alternating current. In some embodiments, the buzzer, the speaker, or its battery can be powered using solar energy, wind energy, kinetic energy of the liquid within the hose, and the like. The buzzer or speaker can make a sound when it is energized, thus acting as a warning and guidance.

In some embodiments, the sensing device may be further provided on the basis of the arrangement of the light-emitting device or the sound-emitting device on the surface of the hose.

For example, it is possible to control the continuous or intermittent illumination of the illumination device, the continuous or intermittent sounding of the sounding device, or the simultaneous reaction of the illumination device and the sounding device, thereby providing an alert or guidance function. For example, the sensing device may control the light emitting device to emit light after feeling that it enters the night, and feel that the light emitting device stops lighting after entering the daytime.

In some embodiments, the hose without the luminous layer or the reflective layer may be fabricated first, and the luminous layer or the reflective layer on the hose may be replaced by a night light or reflective fitting disposed on a common tube. Luminous or reflective accessories include, but are not limited to, luminous or reflective collars, luminous or reflective tape, luminous or reflective coatings. Among them, the luminous or reflective collar can be easily fixed on the surface of the hose.

The luminous or reflective tape can also be attached to the surface of the hose in the form of a strip in the axial direction or in a ring-like circumferential interval, thereby realizing the luminous or reflective function of the hose.

In some embodiments, to prevent clogging of the hose due to twisting or folding, or to limit the free rolling of the hose, a support restraining structure may be added to the exterior of the hose. For example, in order to prevent clogging of the hose, a support frame may be provided on the surface of the hose, which is made of a hard material and has a circular structure inside, and the hose can be kept at all times by fixing the surface of the hose to the support frame. It is rounded to facilitate the circulation of liquid inside the hose. Wherein, the support frame can be arranged in plurality with a certain interval between each other. The support frame can also have any structure such as a square shape or an elliptical shape, as long as the hose can maintain a certain flow cross section. The surface of the hose can be fixed to the support frame by means of adhesive fixing, pressing and fixing. In some embodiments, to limit the free rolling of the hose, a restraining frame may be provided on the hose, the hose being coupled to the restraining frame. At the same time, the restraining frame is fixed to the ground so that the hose is placed on the designated line. Among them, the restraining frame can have various forms. For example, the hose can be attached to the restraining frame, or the hose can only be placed on the restraining frame, and the like. The restraining frame and the ground may also be unfixed. For example, the restraining frame is placed only on the ground and remains stationary by the greater friction between it and the ground. Further, the restraining frame may also be connected to other objects such as a wall, a stone, or the like.

In some embodiments, a monitor can be placed on the hose in order to be able to monitor the hose for damage and liquid leakage. The monitor includes, but is not limited to, a hose flow monitor, a hose pressure monitor, and the like. For example, multiple hose flow monitors or hose pressure monitors can be placed on the hose to measure the flow or pressure of the hose at multiple locations. If the measured hose flow or pressure differs greatly, the hose between the multiple monitors is likely to be damaged.
